Thousands of flights canceled again in Northeast

Airlines are canceling thousands of flights, mostly in the Northeast U.S., because of snow and freezing rain.

FlightAware said more than 2,600 flights had been canceled as Wednesday morning (and more than 2,100 flights delayed). That follows almost 2,000 cancellations on Tuesday and another 2,500 on Monday.

Most of the canceled flights were from the New York-area airports, Boston, Chicago, Philadelphia, and Washington. Regional airline Cape Air alone canceled more than 200 flights, including nearly every flight planned from airports in Massachusetts.

United Airlines warned that the disruptions will affect flights in the Midwest, including Chicago and Cleveland, too. United and other airlines are allowing passengers to change their tickets without the usual change fees.
